This invention relates kto new and useful.

improvements in window locks to maintain same in locked position while'the sashes are partially separated to facilitate Ventilating of a room without subjecting same accessible to unauthorized entry.

-Another object of the invention comprehends the provision and arrangement of dual lock members whereby both sashes will vbe rigidly held in adjusted position;

A Yfurther object of the invention embodies an operating lever for contrdlling the dual locking members.

More specifically stated the window sashes are provided with attaching plates for con nection with the locking members.

With the above and other objects 1n view.,A Y the.y invention further consists of the following novel features and details of' construction, to be hereinafter more fully described', illustrated in the accompanying drawings and pointedf'out in the appended claims.V

In the drawings 4 Figure 1 is a fragmentaryelevation of the adj acent'portions of the sashes for al window showing the present invention applied and in use.

. Figure 2 is a horizontal sectional view taken Y Q6 on line 2-2 of Figure 1.

Figure 3 is a detail sectional view taken on line 3 3 of Figure 1.

v Figure 4 is a sectional View taken online Y 4-'4 of Figure 2.

'l Referringv to the drawings in detail wherein like characters of reference denote corre-y sponding parts, the reference character 10 indicates generally a window frame having .upper and lower sashes 11 and 12 respectively slidably mounted upon'the opposite sides of a partingstrip 13. Thepinnermost or lower sash is held against the parting strip byst'ops 14. The latter willbe again'alludedto in the following description of the invention.`

In carrying out the invention, I provideaVV housing 14 having av tab orear 15 laterally-v projecting from the jbottom thereof: and which is apertured to accommodate vfastening elements to 'secure the housingupon the upper side of the upper rail ofthe lowermost or innersash' ini the manner s'howninFigures 11,2 and' 8'y of the drawings.r -f f Gear members 16 and 17 lying flush against the' upper surfaceofthe bottoni wall of lthe honsingand intermesh'ed :in the manner suggeste'd' in lFigures Av2 and 4 of the Vdrawings are designed for simultaneous operation in different directions- .-QLoc-king I{I`1en1ber'sV generally Yindicated l'as' lat 18; "'are; provided with vertically i andjfh'orizontally disposed f -portions V19 `4andf`2-0Il`lgThefvertically d'is'- posedfportions offthelocking'membersare l fixed to said gea-rs1.` and1r journaled within the bottoni wall'iof the housing.

VThose portions of the'uppe'r sash y l1 and sash stop 14 are gouged or otherwise cut away .immediately behind the elongated i horizontally disposed slots 29 to facilitate .l5 permit of the desired amount of ventilationf" Y3u Within, said housingflocking members. of

Incident to the arran ement and association of the gear mem ers,Y rack bar 5 and locking members, it is tov be noted that in a single operation of the fulcrum lever 23, bothof the locking 'levers are operated in different Y directions to, lockfboth s'ashes against. displacement. Through the several 10 adjustments afforded by the presen'tfinven tion, it is to be noted thatfboth or-"eitherofi-rv the sashes may be elevated or otherwise separated from the adjacent portions of thev'vinf dow frame and locked insuch positions to The invention is susceptiblev of various changes in its form, proportions and minor detailsgof construction, and the right is herein reserved to make such changes as properly 20 fall Within the scope of the appended claim.
